Dianthus 'Frost Fire' is part of the very hardy Cheddar Pink series of perennials. This cultivar is gorgeous with scarlet double flowers that bloom radiantly under the summer sun. Linear, blue-green foliage looks cool in contrast to its red display and stands out nicely on its own the rest of the season. Dianthus 'Frost Fire' is stunning as part of a mixed low border. It will also spread nicely and fill in rock and cottage gardens. Be sure to plant it, where you can benefit from its sweet scent, or simply cut flowers to enjoy them indoors too.
